Hi, everyone. My name is Julia, and my husband and I just had a 21-foot x 52 inch above ground pool professionally installed about three weeks ago. Since day one after the pool was filled, water has been puddling up around it. My husband did say that he thinks he overfilled it and then it rained for several days after installation. It seems like the water will simply not go away. Also, the water level drops every few days, and he refills it. Our concern is that maybe our new pool is leaking although tonight I noticed that when the pump was running, water was coming out of the skimmer basket. He had just put water in the pool again. In a 52-inch deep pool, how much should he fill the pool? Also, does it sound like we may have a leak?
